Throttle Body Spacers

I am unaware of it being done on Tahoe/Yukon/Suburban/Yukon XL/Escalade, but I know it has been done on Silverados. Here are some links:

I did a cursory search of the TYF forums, but didn't find anything here.

Good luck.

Should be pretty easy to do.

Has anyone ever converted a 01 Yukon 5.3 with standard vacuum brake booster to hydro boost

Since many models came factory with hydro boost its a very easy swap.

Just to bump a 10 year old thread.

I've heard people swear that TBS actually work, and that they can feel it. This may be from one of two things that actually happen.
1. It relearned. Especially if you cleaned a part of the air intake or happened to do a relearn with some other intake improvement, or even colder weather.
2. What adding a spacer WILL DO is add distance between the TB and the manifold. On a DBC/99-02, you are taking out about an inch of slack in the throttle cable, (where there is no adjustment of the throttle cable tension). The gas pedal is not supposed to accelerate as soon as you hit it. There is some travel designed into the pedal from the factory. You are removing some of that slack, which WOULD cause your throttle cable to be tighter, your throttle body to be opened sooner, and could be misinterpreted as engine responsiveness. Your engine is not responding quicker, your gas pedal is.
